hello you have what you call a "shut down circut" it is for safety and when one of the internal boards gets shorted or is not working properly, service doc reads as follows
7 Blinks SOS: Pin 93 of the MPU IC9003 monitors the status of the SC, SU, SD board. During normal operation, the photo-coupler PC6480 outputs a low to pin 93. If the SC, SU, or SD board becomes defective, a high is provided to pin 93. As a result, the unit shuts down and the power LED blinks 7 times
thiera blinking 7 times is cuase by a fualt in sc,su,sd boards

Panasonic sent a repairman out with the correct part after telling them about the seven blinks. The unit was out of warranty. They rock. Call 800-211-7262 or 800-524-1448 1

I don't know but I'm having a similar problem. I have a plasma
TH-50PZ77U. It will run for a while and then shuts off. Also, the volume goes up and up and then it shuts off at times. Like I have a ghost here. I had both of my sat. recievers replaced. It seems to get worse over time with shut down. I called panasonic and they had no info and denied this was an issue but I beg to differ from my research here online. It's only a few years and we paid lots of $$$. They gave me a # for service 1 hour away!
